DM/DI Plant

Advanced DM & DI Water Plants: Engineering Ultra-Pure Water Solutions

In high-precision industries, standard filtration isn’t enough. Total Dissolved Solids (TDS) and mineral ions can cause catastrophic equipment failure or contaminate sensitive chemical batches.
Our Deminerialization (DM) and Deionization (DI) Plants are designed to remove nearly all ionized minerals and salts from water, providing the ultra-pure water (UPW) necessary for high-pressure boilers, pharmaceutical formulations, and semiconductor manufacturing.

DM Vs. DI: Whats The Diffrence?

While the terms are often used interchangeably, they refer to the process of removing mineral ions:
• DM (Demineralization): A broader term for any process that removes minerals (can include RO or Distillation).
• DI (Deionization): Specifically refers to the Ion Exchange process using resins to trade H+ and OH- ions for mineral contaminants.

How Our DM Systems Work

Our plants utilize a multi-stage ion exchange process to achieve maximum purity:
1. Cation Exchange: Water passes through a Strong Acid Cation (SAC) resin, replacing positive ions (Calcium, Magnesium, Sodium) with Hydrogen (H+).
2. Degasification (Optional): Removes dissolved $CO_2$ to reduce the load on the next stage and save on chemicals.
3. Anion Exchange: Water flows through a Strong Base Anion (SBA) resin, replacing negative ions (Chloride, Sulfates, Silica) with Hydroxyl (OH–).
4. Mixed Bed Polishing: For ultra-high purity, water passes through a single vessel containing both resins, achieving conductivity levels of < 1.0 µS/cm.
